MINE-CAR.

Specicaton of Letters Patent.

Patented May l 1, 1909.

Application filed August 19, 1908. vSerial No. 449,224.

To all whom it may concern.'

Be it known that l, Gnonen L. BELL, a citizen of the United States, residing at Ell: Valley, in the county of Campbell and State of Tennessee, have invented certain new and useful improvements in Mine-Cars, of which the following is a specification.

My invention relates to improvements in mining cars and particularly to the construction or' axles and lubricating means for the journals thereof'.

The object of the invention is primarily to prolong the life of the cars of this character by providing the axles with wearing members which may be easily detached when worn and new members substituted therefor.

The invention further has for its object provision for lubricating the wearing surl'aces of the journals, which means will supply the oil ellectively, and will not require frequent replenishing thus saving time and trouble.

The invention consists in certain novel features of constructions and arrangement of parts of the axles of the car of this character and also a lubricating device for supplying the lubricant to the wearing surfaces.

ln the accompanying drawings l have illustrated one example of the physical embodiment on myinvention constructed according to thebest mode l have so lar devised for the practical application of the principles.

My invention is applicable to any of the mining cars now in general use and l have illustrated its application to a common form of car.

In the drawings: `Figure 1 is a side elevation of a mining car having the invention applied thereto. lig. 2 is a sectional view on line 2, 2 in Fig. 1, and Eig. 3 is a sectional view of a pair of wheels, and showing their connection with the axle. V

The numeral 1 designates the car body of the usual form of mining car which is supported upon the wheels 2, 2 5 3, the axle proper; 4, 4, reduced portions of the axle referably angular in cross section and l'ormed with shoulders 4, 4'; 5, 5, the end portions or spindles of the axle circular in cross section; 5 grooves in the spindle 5; 6, 6, a pair of sleeves as a whole; 7, 7, a tubular portion of said sleeves rectangular in cross section and adapted to lit the portion 4 of the axle; 8, 8, a tubular ortion ol said sleeves surrounding the spin e 5 of the axle and provided with openings 9 therein; 10, 10, enlarged portions of the sleeves 6 each having therein an oil duct or passage 11; 12, 12, annular grooves formed in the periphery of the spindles and occurring in line with passage 11 oi the enlarged portion 10 13, 13, cotter pins passed through apertures in the ends of the spindle 5 to secure the wheels 14 against lateral movement and displacement on the axles 15, 15, caps secured by bolts 16 to the wheels 14, preferably at the junction of the spokes 17 with the wheel hub. rlhe axles are secured to the car body by means of straps 18.

The numerals 20, 2() designate oil cups secured at the side of the car body; 21 are tubes or pipes extending from the oil cup to the enlarged portions 1G of the sleeve 6 and opening into the passage 11 of said enlarged portions; 22, clips securing the pipes 21 to the side of the car, 23, a band or strap for securing the oil cup to the car, 24, a removable cap for the oil cup and 25, ears forming ad ditional means whereby the oil cup is fastened to the side of the car.

Tt will be observed that the spindle 5 extends beyond the ends of the sleeve 8 which sleeve is flush with the line of the wheel hub and constitutes the journal for the wheel 14. The cotter pins 13 are ol' sullicient length to prevent the wheel hubs moving oil of the journal or bearing sleeve S. The sleeves 6 are thus held in position against lateral motion between the shoulders 4 and the pins 13, and are held against rotation by the angular formation of the parts 4 and 7. The caps 15 are cored out at 15 and form chambers around the ends ol' the journal and the spindle 8. These caps are eli'ectual closures against the admission of dust or grit to the journal bearings.

The operation of the lubricating device is apparent. The oil cups 20 being filled with oil and tightly closed by means of caps 24, oil flows down through pipes 21 through passages 11 into the annular grooves 12 and the longitudinal grooves 5 and also into the aperture 9 in the journal bearing or sleeve 8, thus thoroughly lubricating the journal bearing surfaces.

It will be understood that the journal bearing sleeves 6 are held stationary on the axles and that the wheels revolve on the journal `portions 8 as journals. Should the journals ecome worn at any time the sleeve may be taken off the axle and replaced by a new one at slight ex ense in time and labor. The enlarged portions 1() of the sleeves 6 form effective braces and provide a rigid connection between the axles andthe car body. The pipes 21 also form braces between the axles and car body in that they tend to keep the axles properly spaced apart.

From the foregoing description taken in connection with the drawings it becomes obvious that I have produced an improved mining car which fulls the conditions set forth as the objects of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

l. The combination with a pair of car axles, of wheels, a pair of oil cups carried by the car on each side thereof, two oil pipes leading from each cup to the journals, and said ournals being provided with vertical extensions having passages to receive the oil.

2. The combination with a car and its axles, of sleeves secured on the axles and forming journal bearings for the car wheels, enlarged portions on the sleeves engaging the car body as a brace, oil passages in said enlarged portions, oil cups carried by the car, and oil pipes extending from said cups to the passages in the enlarged portions of the sleeves said oil cups being connected to the side of the car above the axles and a single cup being employed to supply the oil to the journals of said axles.

3. The combination with an axle having reduced `ends and formed with a pair of shoulders, of sleeves secured thereon, and provided with journalbearing surfaces, wheels on the journal bearings and a cotter pin for securing the` wheels and journals against lateral movement said sleeves being formed each with an enlarged portion provided with a vertical oil passage, oil feeding pipes leading to said passages and a single oil cup connected to each side of the car and arranged to feed the oil to the oil passages of the sleeve.

4. The combination with an axle having reduced ends, a portion of which ends are angular in cross section, and shoulders on the axle, of sleeves adapted to iit said angular portions and abut against said shoulders, journal bearing surfaces formed on the sleeves and cotter pins passed through apertures in the axle ends said sleeves being formed each with an enlarged portion provided with a vertical oil passage, oil feeding pipes leading to said passages and a single oil cup connected to each side of the car and arranged to feed the oil to the oil passages of the sleeve.

5. The combination of a car, a pair of oil cups connected to said car and arranged one on each side thereof, a pair of oil feeding pipes leading from each oil cup, sleeves having oil passages to receive said pipes, axles having reduced ends fitting in said sleeves, cotter pins engaging the ends of said axles, wheels mounted on the ends of the sleeves,

and caps carried by the wheels and covering and protecting the ends of the axles.

5. In a mine car, the combination of a pair of axles each having a central plane portion, a contiguous tapered angular portion, oil grooves at the outer ends of the angular portions, tapered end spindles formed with longitudinal oil grooves, cotter pins passing through the ends of the spindles, sleeves having an angular portion to fit the angular portion of the axle, a tapered cylindrical portion to ht the tapered spindles of the axles, oil feeding openings connected with the transverse grooves in the spindles, sleeves having the oil passages leading to the oil receiving grooves of the axles, and oil supplying means connected to the car and supplying the oil to said sleeves.

In testimony whereof I aflix my signature, in presence of two witnesses.
